802.11n Wireless and Gigabit Ethernet USB Device Server

The DS-520AN is a USB Device Server supporting 802.11n Wireless LAN or Gigabit Ethernet Wired LAN Networks. Any USB device can be used over a wired/wireless network with the DS-520AN just as though it was connected to a computer.

Gigabit Ethernet USB Device

Office equipment such as USB scanners, multi-function printers (MFPs), dongles, hard disk drives, and cameras etc. frequently lack a wireless interface thus making them unavailable to connected devices such as computers, tablets, and smartphones. The DS-520AN Wireless USB Device Server replaces the USB cable with an enterprise-secure wireless or wired LAN connection.

The DS-520AN Supports Enterprise Security (IEEE802.1X) , Full-Speed / High-Speed Isochronous Transfers for real-time data transfers from USB cameras and speakers. The 802.11n wireless connection supports up to 300Mbps or the wired Gigabit Ethernet connection supports up to 1Gbps throughput.
